In 1989 and 1990 two field trials were carried out each year in Oxford County to determine the effects of kelp, molasses and 71B fertilizer solution (1990 only) on soybean plant growth and seed yield in an aeration tillage system. Results from two years of study indicate that the use of kelp and/or molasses and/or 71B fertilizer solution as a seed and/or foliar treatment in an aeration tillage system did not significantly affect the growth and yield of soybeans.
